I am very new to reactJs and just started to learn the features of reactJS. I am trying to figure out a way to pass the value from nodeJS to reactJS via server side rendering concept.
In the below example, I was able to define a react component and add it in server and render it in UI but I am not sure how to pass the data to the component that can be used inside the component render function.
client.js
var React=require('react');
var ReactDOM=require('react-dom');
var Component=require('./Component.jsx');
ReactDOM.render(
React.createElement(Component),document
);
Component.jsx
var React=require('react'),
Request=require('superagent')
module.exports = React.createClass({
getInitialState: function () {
return {
};
},
componentWillMount: function () {
},
componentDidMount: function() {
clearInterval(this.intervalID)
},
_handleClick: function () {
alert('You clicked!')
},
render:function(){
return(
<html>
<head>
<title> ReactJS - demo </title>
<link rel='stylesheet' href='/style.css'/>
</head>
<body>
<div>
<h1>react js testing</h1>
<p>This is so cool</p>
<button onClick={this._handleClick}>Click Me!</button>
</div>
<script src='/bundle.js'/>
</body>
</html>
);
}
});
Server.js
require('babel-register')({
presets:['react']
});
var express = require('express');
var app=express();
var React=require('react');
var ReactDOMServer=require('react-dom/server');
var Component=require('./Component.jsx');
app.use(express.static('public'));
app.get('/',function(request,response){
var html=ReactDOMServer.renderToString(
React.createElement(Component)
)
response.send(html)
});
var PORT=4444;
app.listen(PORT,function(){
console.log("Node js listening in port:"+ PORT);
})
Update 1:
I am now able to pass the value to the server side rendered component as below
React.createElement(Component,{object:...})
Now the server side setup works fine.
I need to make this {object:...} available in my client.js also for client side functionality to work. Any idea how to get this value in client.js?
React.createElement
ReactElement createElement(
string/ReactClass type,
[object props],
[children ...]
)
Create and return a new ReactElement of the given type. The type argument can be either an html tag name string (eg. 'div', 'span', etc), or a ReactClass (created via React.createClass).
In the your version in the
React.createElement(Component)
u need use something like
React.createElement(Component, {obj: obj, ...: ...})
